IMPROVEMENT IIN Pltows.

Spceilieation forming part of Letters. Patent No. 32,094, dated April161861.

Salem, in Washtenaw county,A and Stute' of Michigan, have invented a newand useful Improvement upon Gast-Iron Plow-Beams; and I do deel-.irethe' following to be a full and.

exact descriptionthereof, reference being had to the accompanyingdrawings, and to the letters ot' reference marked thereon. l

The nature of invention and improvement consists in the urrangementot'devices, as here inalter described.

Reference being had to the accompanying drawings, like letters referringto like parte, Fi gnre 1 is the beam, with parts fitted together and4secured lLy bolts. Fig. 2 is the beam, separated into two parts, markedBartl land Part 2. Fig. 3 is part 2 inverted te show the face andknuckle on the lnndside of the saine. My improved plow-beam is ofeast-iron, and consists of two parts', (marked ,Part 1 7 und "Part 2 inFig.' 2,) so arranged as to be connected in lap-joint A by carrying backpart 2 upon pnrt 1, so as to bring together the points C C and I) l), bywhich means the inner face of the rear end of. part 2 is brought againstthe flange-bound face F in part I, thel bolt-holes H H H in one partmatching corresponding holes in the other parts. The inner face ot'part. 2 is shown at G in Fig. 3, which is part inverted, asabovedescribed. .The two faces being thus put together, the knuckle K inFig. 3, projecting from thefaceG, fits into the socket L, part 1,Fig. 2.The projection M otpart l lits into .the recess N of p'art 2. TheshoulderA C of parti! is brought against C in part 1, and the curved endG D ot part 2 lits against and' Within the corresponding flange C D ofpart l. 'lille parts being thus put together are secured by boltspassing through holes ll' H 1I, parts land 2, Fig. 2. The bolts areshown at 0 O O, Fig. 1.' Before the bolts are fully screwed up awedge-shaped' key, B, Fi g. 1, is inserted into the mortise I, by meansot' which the faces G and F may be more or less separated at the backpart of the joint, and the angle or position ot' the beam,part 2,adjusted and the dralt regulated accordingly.

A. slight adjustment of the key B making considerable change in thedraft without crossstrain ofthe beam ,several horses may be workedabreast with advantage and safety,and by the -arran gementot knuckleprojections, and flange a lirin and secure joint is obtained withoutstrain upon the bolts.

f I-do not claim a disjointed benin as such, nor

tlie lap and knuckle joint; but

WhatI do claim, and desire to secure by Let- Thejwedge B, knuckle, K.,fitting into the socket L, lla-nge O D, projection M, fitting-intorecess N, the parts 1 and 2, having corresponding faces and boltholes,the whole bein g made, arranged, and devised substantially in the mannerand for the purposes set forth and described.
